Q.1 How do we influence the environment? Is deforestation one of the

Environmental issue? Why?​

Answer 1

Answer:

Deforestation

Deforestation can have wide reaching environmental effects. Forests provide habitat and shelter for a substantial number of terrestrial plants and animals. Trees help curb erosion by allowing soil to accumulate around their root systems, and provide canopy over the forest floor so that heavy rains have less impact. Forests also provide many services, including an important role in all of our natural ecological cycles (carbon, nitrogen, oxygen, water and nutrient), serving as a major store of carbon, and acting as a filter for clean watersheds.

The motivations that result in deforestation are very complex, primarily due to the nature of the countries and regions where it predominantly occurs. The leading land-use change associated with deforestation is agricultural expansion, which includes forest conversion for permanent cropping, cattle ranching, shifting cultivation, and/or colonization. Logging practices for pulp and timber, both legal and illegal, can also contribute to forest loss if regeneration is not allowed to occur. Yet, oftentimes, it is a shear growth in population that increases demand for food, fuel, and subsistence; a basic way of life for many within tropical and less developed countries.

Deforestation currently accounts for 25 percent of man-made emissions of carbon dioxide worldwide. It also contributes to the spread of desertification—arid, desert-like conditions—across the globe which further affects agricultural productivity. While there is some disagreement as to the causes and extent of desertification, wood collection, over­grazing, and other human activities are thought to be important factors.

Estimates of global rates of deforestation vary widely, but the concern is most serious in tropical areas and developing countries. From 1990 to 2005, three percent of the world’s total forest area was lost. The United Nations FAO estimates that tropical forests are losing an estimated 10.4 million hectares each year, with more than half of losses occuring in only two countries—Brazil and Indonesia.

Unfortunately, international concern over forest loss can have little effect when populations have few options for survival. Efforts to promote alternative sources of income from forested lands, including medicinal and other marketable prod­ucts, have not yet provided sufficient incentive to prevent deforestation in many areas.

Answer 2

Answer:

*The environment can influence peoples' behavior and motivation to act. ... The environment can influence mood. For example, the results of several research studies reveal that rooms with bright light, both natural and artificial, can improve health outcomes such as depression, agitation, and sleep.

Farming, grazing of livestock, mining, and drilling combined account for more than half of all deforestation. Forestry practices, wildfires and, in small part, urbanization account for the rest. In Malaysia and Indonesia, forests are cut down to make way for producing palm oil, which can be found in everything from shampoo to saltines. In the Amazon, cattle ranching and farms—particularly soy plantations—are key culprits.

Logging operations, which provide the world’s wood and paper products, also fell countless trees each year. Loggers, some of them acting illegally, also build roads to access more and more remote forests—which leads to further deforestation. Forests are also cut as a result of growing urban sprawl as land is developed for homes.

Not all deforestation is intentional. Some is caused by a combination of human and natural factors like wildfires and overgrazing, which may prevent the growth of young trees.
